Our company has been using Dynomotion products for years. The incredible and continuous support we have received is one of the major reasons why we keep coming back to use Tom's fantastic control cards.

Very good support. Make changes in to soft opening more possibility, and friendly support maker very helping. Also, the quality of the products is superior and the software is very user-friendly. I recommend this product.

Used KFlop and Kanalog to upgrade a 1998 Dyna EM3116 Mill to the 21st century. Overall a simple and smooth experience. The only issues I had were either of my own making or with old components. The Dynomotion stuff is top notch and performs exceptionally at a fantastic price point. I'm now actively looking for more old machines to give the dynomotion treatment!

Good hardware, bad software and support. I work with CNC control systems as a part of my job. This system is difficult to setup due to a lack of proper documentation. The documentation available is not well organized and not very clear. I use and have written technical manuals for many years, these are terrible. The company cannot decide if it is making a product for hobbyists who want to sit around figuring things out or if they want to make a product for a professional who should be able to ... Read More

Good hardware, bad software and support. I work with CNC control systems as a part of my job. This system is difficult to setup due to a lack of proper documentation. The documentation available is not well organized and not very clear. I use and have written technical manuals for many years, these are terrible. The company cannot decide if it is making a product for hobbyists who want to sit around figuring things out or if they want to make a product for a professional who should be able to use a manual to understand fully how a product works and design a system using that documentation. I have worked with products that I did not touch until I had completely designed the system they go it, handed it all to a technician to assemble, then load software and test all in the span of a few weeks. I have been working with this for 3 months and still am having issues. For instance, their "PID" control for servo feedback is not a PID control. It's a PI control with the ability to add velocity damping due to the D gain being applied to differentiated position instead of differentiated error. Was told this was somehow better by Tom. Completely changes the way a PID loop functions.

Hi Mike, bad support?? and I suppose that also seems expensive too... I do not feel identified with your comment (and think i´m not the only one), and feel that it is a contempt to the work that these people do, if an amateur can configure this hardware and a professional does not, I´m so sorry very much for the professional, it´s not a "ready to fly" products but is more powerful and adaptable that other options in the market.

I agree that it is more adaptable than other products on the market. That's why I ended up using it. However, when you've used some of the other products available that have been developed by larger, more experienced companies you see that the documentation and support for this is limited (extremely). The simple fact that you have to wait, sometimes days, for an email response about any issues is dreadful to me. No real company releases a product and expects customers to have to wait ...

The simple fact that you have to wait, sometimes days, for an email response about any issues is dreadful to me. No real company releases a product and expects customers to have to wait for email support. Telephone support is absolutely necessary. Also, Tom has told me that he will not assist in tuning PID even though his PID is not implemented per industry standard practice. Derivative feedback is not performed after error is calculated, but is purely rate of position , not rate of error... Just one of many problems. Here's a manual of a product we use that is very easy to setup and use. It is not a complete CNC system, just a servo amplifier, but it has many programmable features and is just as complex in my opinion. https://www.copleycontrols.com/wp-content/uploads/2018/02/XTL-XSJ-Xenus_User_Guide-Manual.pdf Perhaps Tom could take note and improve his manuals?

I think a lot of people here have experience running CNC machines. If you do, you'll understand this: CNC machines have the ability to show you the distance remaining to move before you reach your next commanded position. In other words, if your G code commands a move from X0. to X10. while your machine is traversing between those points you can access a mode in which the controls displays the distance remaining before you reach X10. I was just told by Tom that his product does not have ... Read More

I was just told by Tom that his product does not have this capability and that he "can't think of a simple solution". Sound like good support to you? If anyone else has been able to implement a To Go read out, please tell Tom how to do it so he can tell me. Unbelievable.... have you ever run a CNC Tom?

If anyone gives this product less than a 5, it is because they do not understand the technical aspects of this technology. No manufacturer makes anything even close to the capability and versatility these boards are capable of. Yes they are complex, however the rewards are great too using Dynomotion products. The quality of this product along with support (manuals and Forums) is superb!I use Kflop, Kstep and Kconnect boards and they are worth every cent.

The example VB.net example programs do not compile. This has set me back considerably.

It is important that libraries and example programs work as claimed. While I understand the difficulty of creating such a library and example programs, others have had the same problems as well -- which have also not been resolved.
